    GTX 760 is it on par with the GTX 680?

    Also,

    Is the 760 a re-badged GTX 680?

    How close are the gtx 760 and 680?

    no - a GTX 770 is a rebadged GTX 680 (an overclocked version)


    the GTX 760 is slightly slower than a gtx 670 (and comparable to a GTX 660Ti)

    No the 760 is not as fast as a 680, it's a bit slower than a 670.

    Re: GTX 760 is it on par with the GTX 680?

    760 is modified 670.

    The GeForce GTX 760 has elicited mixed reactions here in the HEXUS labs. It's hard to argue against the fact that this is one of the best-performing cards currently available at around the £200 mark, but me, personally, I'm a little disappointed.

    Nintendo's Wii U is struggling, Sony's PlayStation 4 seems to be preoccupied worrying about the competition, and Microsoft's Xbox One is making it up as it goes along. Surely it's time for PC gaming to strike while the iron is hot and deliver true next-generation experiences?

    Apparently not. AMD's still pushing the 18-month-old Radeon HD 7000-series, and, while Nvidia has made the jump from GTX 600 to GTX 700, it's still banging on the ol' Kepler drum. GTX 770 proved to be a higher-clocked version of the incumbent GTX 680 and the newly-unveiled GTX 760 is ultimately a year-old GTX 670 that happens to have misplaced an SMX unit; meaning 192 fewer processor cores, 16 fewer texture units and an increase in core frequency to compensate.

    This link says it is a rebadge?

    that link is very wrong:


    http://hexus.net/tech/reviews/graphi...force-gtx-760/

    hexus very own review

    and your link is about a waterblock - and whilst the family of chips are similar GK104 - waterblocks are board mounted , which means that you can use the same warterblock for a number of reference boards (not custom boards).

    Yes, but so are the GTX670 and the GTX660Ti. The GTX760 is a further cut-down version of the GTX670, as is the GTX660Ti, but they have different sections cut back.

    So yes, it's the fourth graphics card to use GK104, the first of which was the GTX680. But that doesn't mean it's anything like a GTX680 in performance.

    Re: GTX 760 is it on par with the GTX 680?

    The 760 is a variant of the 680. The overclocked 760's can beat a stock 680

    770 has a slight increased clock on the 680 and faster memory (hence it dubbed an overclocked 680)
    680 has 8 SMX clusters (1536)(256-bit)(1006MHz)
    670 has 7 SMX clusters (1344) (256-bit)(915MHz)
    660Ti has 7 SMX clusters (1344) (192-bit) (915MHz)

    760 6 SMX clusters (1152) (256-bit) (980Mhz)

    So in essence the 760 is a 670 that has less cores but a bump in clock to compete

    But the 680 and 760 only have like 10 frames difference?

    Re: GTX 760 is it on par with the GTX 680?

    The fab process in now matured so the quality of the chips has a greater yield. (rumours suggest) The 670 and the 660Ti where in essence lower quality 680's that where restricted with various techniques as listed, either because they where not good enough for a 680, or to minimise risk of failures.

    The new 770 and 760 are essentially superior 680's with the 760's likely to be the slightly inferior quality yields, but as they all seem to be clocking over 1.1GHz with ease, you can see how they have got to grips with the fab process.

    The 760 can overclock to 10 - 20% which in the extremes can be superior to a stock 680, but at stock seems to be just below a 670

    Depends on game, detail level/options and resolution.
    in general yes the gtx760 is only a bit slower, it's just nvidia binning chips to take failed chips and turn them into something useful.

    It's standard in all chip production, when you're making things so small they are measured in nanometres it's impossible to get 100% yields, so you design the chips in modular sections so if one area has a fault you can just mask that area off and the chip still works.

    Scainer almost had it right, it's not a variant of the gtx680 it's a variant of the GK104 which the GTX680 is also a variant of.
    gtx 770 & 680, full chip nothing masked off. (1536streams, 32ROPs, 256bit ram bandwidth)
    gtx 670, 1 stream cluster masked off (1344streams, 32ROPs, 256bit ram bandwidth)
    gtx 760, 2 strem clusters masked off (1152streams, 32ROPs, 256bit ram bandwidth)
    gtx 660ti, 1 stream cluster + 1 memory controller + 1 raster operation cluster masked off (1344streams, 24ROPs, 192bit ram bandwidth)

    The difference between the gtx770 and gtx680 is not so much that the gpu runs faster it's the improved VRM circuit on the actual card that allow the gpu to run faster reliably.

    Both the 600 and 700 series are rather odd, in that nvidia seem to have dropped it's "normal" naming system, normally the top end x80 and x70 are the top end chip with the x80 being full and the x70 being a binned chip, the x60 and x50 is a separate chip that is basically a simplified version.

    However this time round the same 2nd tier chip (GK104) has been used for GTX 680, GTX 670, GTX 660ti, GTX 770, GTX 760
    Three main reasons for this,
    1 the AMD 79xx haven't performed as well as expected so nvidia hasn't had to push so hard.
    2 the keplar chips (both GK110 and GK106) have actually performed better than expected.
    3 The GK110 has turned out to be more expensive to produce than expected.
    This time the Titan is the full top end GK110 chip, the gtx780 is the GK110 with one clusted masked off.

    The GK104 is turning out to be a really amazing chip in the same way that the G92 was and like the G92 nvidia are going to milk it for all it's worth.
    (the G92 was used in the 8800gts 512mb, 8800gt, 8800gs, 9800gt, 9800gtx, 9800gtx+, 9800GX2, gtx240, gts250, gts250 green)

    All told the 700 series is little more than binned 600series chips put on slightly beefier cards to allow nvidia to eek a bit faster clock rates and faster vram, that's not to say they are bad far from it.
    The gtx760 at just over £210 is an amazing performing card for the price, one thing to note is that while the x60 or x600 was always a mid range gaming card in the line up the nvidia has been pushing this general model into the higher end in terms of both performance and price with the more mid range £150ish cards becoming the x50 this in turn has let them push the price of the top end cards that bit higher.

    EDIT:I suspect that many of these gtx760 gk104's are off the original run as there where no 2 stream cluster masked gk104's in the 600 line up AFAIK which is probably part of the lower price (the gtx660ti was £250 at launch)
